But when I change the ODBC Setup from ODBC SqlServer 11 (MSODBCSQL11.DLL) to SQLSRV32.dll it works fine.
My application with SQLSRV32.dll has been running smoothly for more than 10 years on all WINDOWS (XP,7,10) and all SQLSERVER versions (2000-2014)

I now upgraded a client database from SQLSERVER 2000 TO SQLSERVER 2012. The ODBC SQL Server MSODBCSQL11.DLL fails.
